add weight to search feilds

lawrence whittemore asked on May 15, 2015 16:18

Is there a way to add weight to different fields in the search so that keywords in those fields would make the document rank higher? A client would like the document name to have more weight than other fields.

If I recall correctly it was on a future enhancement list a year or so ago, not sure if that functionality was added as of yet. Can you modify the index to suit your needs ?

I'm not sure how to modify the index. If it's not available we can probably come up with an alternate solution to meet the client needs.

Event easier, in Lucene.net you can boost a value by adding "^#" to the search field

Ex: ProductColor('Red')^2 ProductSize('Small') ProductShape('Circle')^.5

Would result in Product Color "Red" Matches being 2x heavier in weight than the size, and shape would be half the weight as Size.

We just modified the Smart Search Filter, added a "Boost" Field to the web part, and then appended "^"+Boost to the drop down values. Worked like a charm!
